Answer:
440
Explanation:
If 50% of the total gum balls are red which is 220, then the other 50% is 220.
If the perimeters are equal, you can form an equation to find x:
x + x + 12 + x + x + 12 = x + 11 + x + 11 + x + 16
4x + 24 = 3x + 38
- 3x
x + 24 = 38
- 24
x = 14
Now you can substitute the x value into the perimeter:
(4 × 14) + 24
56 + 24 = 80 cm
(3 × 14) + 38
42 + 38 = 80 cm
So the perimeter would be 80 cm.
I hope this helps!
Answer:
2 2/9
Step-by-step explanation:
It would be ten because 40 divided by 4 is ten
Answer:
BC = 10.24
Step-by-step explanation:
You can use the Pythagoras theorem for this question
+ 
= 
a = 8cm
b = ???
c = 13cm
We will solve for B (length BC)
+ =
+ = 
Rearrange for b
= -
= 105
b = 
b = 10.24
